When 2D layered materials are made thinner (i.e., at the atomic scale), their properties can dramatically change, sometimes resulting in the emergence of entirely new features and in the loss of others. While new or emerging ...
Transistors based on semiconductor materials are widely used electronic components with many remarkable properties. For instance, they have a nonreciprocal electrical response, which means that they can isolate two parts ...
(Phys.org) —Most materials behave very differently in bulk (3D) form than they do in monolayer (2D) form. The difference occurs because of weak forces holding the multiple layers of a bulk material together, which results ...
Strain-induced crystallization can strengthen, toughen, and facilitate an elastocaloric effect in elastomers. The resulting crystallinity can be induced by mechanical stretching in common elastomers that are typically below ...
True to Moore's Law, the number of transistors on a microchip has doubled every year since the 1960s. But this trajectory is predicted to soon plateau because silicon—the backbone of modern transistors—loses its electrical ...

Two-dimensional materials, which consist of just a single layer of atoms, can be packed together more densely than conventional materials, so they could be used to make transistors, solar cells, LEDs, and other devices that ...

Titanium is strong and lightweight, boasting the highest strength to weight ratio of any structural metal. But processing it while maintaining a good balance of strength and ductility—the ability of a metal to be drawn ...

Researchers in China and at UC Davis have measured high conductivity in very thin layers of niobium arsenide, a type of material called a Weyl semimetal. The material has about three times the conductivity of copper at room ...
